Utilization of Pseudomonas sp. from Livestock Slaughterhouse Waste for Biodegradation of Polyethylene Terephthalate Plastic Waste

Abstract

Indonesia is currently facing a significant environmental issue, namely the increasing quantity of plastic pollution, particularly of the polyethylene terephthalate (PET) type. PET is commonly used as the base material for packaging bottles and is recommended for single-use only. Due to its high resistance to biodegradation, unregulated PET waste accumulation poses a substantial environmental threat. The proliferation of PET usage has adverse effects on climate change and environmental pollution. To address these challenges, it is crucial to implement biological control measures by identifying potential bacteria capable of degrading PET, thereby minimizing plastic waste. Pseudomonas sp. bacteria, found in the rumen waste commonly present in Slaughterhouses (RPH), are promising candidates. The rumen contents contain digested feed materials, turning into waste after the animals are slaughtered. Pseudomonas sp. can produce esterase enzymes, enabling them to hydrolyze compounds in plastics, particularly PET. Therefore, research optimization of rumen fluid waste is essential to harness its potential as a biodegradation agent for PET plastic waste.
